FizzBuzz

FizzBuzz

The classic. Walk the numbers 1 to n and, for each, decide what string to add to a list:

• divisible by both 3 and 5 → FizzBuzz
• divisible by 3 → Fizz
• divisible by 5 → Buzz
• otherwise → the number itself, as a string

Check the "both" case first, or a multiple of 15 will be caught by the 3 test alone.
